SPECIFCATION forming part of Letters Patent No. 606,564, dated June 28,1898. Application led October 8, 1897. Serial NO- 654,497- (NO mOdeL) T0all whom, t muy concern:

Be it known' that we, ALBERT LONG and ROBERT FOSTER, of Lawrence, in thecounty of Essex and State of Massachusetts, have invented certainV newand useful Improve-1 ine-nts in Apparatus for Drawing Off in Circlethefollowing is a speciiica.

Combs, of which tion.

This invention relates to circle-combs, and

is hereinafter described in connection Withia wool-comb of the typeknown asthe Noble comb.

The invention has for its object to provide anV improved method lof andmeans for drawing off the wool andforconducting the same from one set ofdrawing-off rolls to the other set. I-leretofore the drawing off hasbeen accomplished byv means of fluted rolls and leather aprons'soYarranged as to take the projecting bers of wool-from Vthe combs andform the same into a sliver, that portion whichis drawn from the' largecomb or `circle being conducted between the leather aprons from thedrawing-off rolls of the large circle to the drawing-O rolls of thesmall circle, Where it combines 'with the wool from the small circle toform the sliver. This method is open to several objections well known.to those skilled in the art of combing WOOL-the two principal onesbeing the wear on the leather aprons andthe frequent breaking of thesliver, caused by the wool from the large circle following the apronsaround instead of passing between the drawing-off rollsof the smallcircle. The wear on the aprons, is very considerable and requires themto be frequentlyrenewed, thus involving expense and trouble. Thebreaking of the sliver is disadvantageous in itself and also because itrequires the stoppage of the comb and consequent loss of time.

By means of the present invention the leather aprons are dispensed withand the drawing off accomplished by smooth surfaced rolls, an improvedconducting device being alsoprovidedlfor conducting the wool from'onedrawing-off headto the other.

The invention consists in the novel features of construction andarrangement-.which will now be explained with the aid of theaccomtherebetween.

Referring to the drawings, Z5 in I Fig. l0 designates the large circleof a'Noble comb, and Z4 one of the small circles. For the purpose ofdrawing the wool from the teeth of the large circle we provide, in placeof the usual-two liuted rolls and leather apron, four smooth-surfacedrolls k3 154 165 7c, arranged in a train and bearing against each otherat three points, so as to have three nips7 on For certain kinds of wooland in certain cases it may su nice to have onlyT three rolls in thishead, but for general work We prefer to have four, as shown. The fibersof wool are drawn, as shown in Fig. l0, from between the teeth on thelarge circle, and passing in the form of a sliver between the rolls ofthe drawing-head they are conducted,

by means'of a conducting device hereinafter described, to the otherdrawing-head adjacent to the ,small circle. Here they A meet Fig. 5represent-s a IOO in this head, smooth-surfaced like those in the otherdrawing-head. The mounting of the rolls in each head is as follows:

c a designate supporting-standards mounted 011 a base t) and broadenedat their upper ends to form tables c c, on which rest the twodrawing-heads d and c, which pivotally surround d riving-shafts fand as.The group of rolls corresponding to the small circle l of the combcomprises a roll g, formed as an enlargement on the upper end of theshaft j", and two other rolls 'r and S. The roll-shafts are providedwith gears o 17 q, whereby the rolls r and s are driven by the roll g.The shaftf is supported in suitable bearings 7L i on the frame e and isprovided below the base Z1 with a gearj, adapted to mesh with a suitabledriving-gear. (Not shown.) Rotary motion is transmitted from the shaftfto the shaft ci by suitable intermeshing gears a* cr" a, receivingmotion from the gea-r In the drawing-head c the roll 7o@ is the driverand the other three are driven by gears from this roll in the samemanner as the rolls in the head (t.

In order that the tension of the rolls in each head upon the sliver maybe adjusted, yielding bearings are provided for the rolls a s and forthe rolls le k1 7J". These bearings are best illustrated in Figs. U to9, which show the construction of the drawing-head d. )tecesses u areformed in the frame of the head rl, and in said recesses are mountedcarriers e u, which are retained in position by overlapping edge platesa a/ lr., bolted to the head, and by the upper and lower walls of therecesses in which the carriers are mounted. To said carriers are boltedbrackets l2 c', having sleeves 112 c2 at their outer ends, which supportand journal the rolls Ir s. The carriers yr 1r are provided withenlarged portions l', forming sockets z', in which are located spiralsprings j. Said springs press against the ends of the sockets andagainst plungerblocks 1", which are backed by adjustingscrews g'. Inthis way the rolls r s are yieldingly actuated toward the roll g, andthe amount of pressure upon the wool sliver is regulated with the adjusting-screws g'. The mounting of the rolls k3 l# 7J in the otherdrawing-head is similar to that of the rolls r s, with the addition of athird yieldinglymounted roll.

The heads are adapted to be moved radially upon their respective shaftsa limited distance in order to adjust the outer surfaces of the rolls tothe circular combs. rlhcy are secured in position by bolts c3, Figs. Gand 7, passing through circular slots in the tables c and screwing intothe heads. and a3 turn in bushings b1, Fig. 5, which pass looselythrough sleeves b, formed on each head, and are secured by means ofset-screws LG in journals on the standards a..

In order that the drawing-rolls of each head may be adjusted toward andaway from their The shafts j" j" in said frame.

respective circles for the purpose of regulating the closeness of thenip, the standards c are provided with slots 0,7 a7, through which passthe' bolts as a8, which clamp said standards to the base h. lVhen,therefore, itis desired to move the drawing-heads bodily, the nuts onsaid bolts are loosened andthe standards, together with their shafts,are moved a small distance, though not sufficiently to disengage thegears underneath thc base l1, the bolts being then tightened up again.

It is to be noted with respect to those drawing-rolls in each head whichare mounted in yielding bearings that both ends of each roll arejournaled in a single carrier, so that the roll is moved bodily insteadof having its ends independently adjustable, which is the practice withthe tinted rolls employed on machines now in use. rlhe improvedconstruction here shown gives an even contact throughout the length ofeach roll and permits of a single adjustment for both bearings of theroll instead of two adjustments, as formerly.

rlhe mounting of both bearings of the roll in a solid frame or carrieris an important feature, since it is essential to the bestrcsults thatthe surfaces of the rolls be, as nearly as possible, exactly parallel atall times. It will further be noted that the bearings of each roll areplaced as near together as possible, and the roll is of very stoutconstruction in order to prevent any possibility of buckling.

The particular arrangement of d rawing-off rolls which we have inventedproduces what may be termed a lock-nip on the wool. This lock-nipconsists in the action produced by two smooth-faced positively-drivenrolls cooperating at separate points with a third positively-drivensmooth-faced roll. ln the case of the drawing-head c of the large circlethe wool is engaged with a double lock-nip-that is, there is thelock-nip produced by the three rolls 7a3 701 7s. and that produced bythe three rolls 7J* h5 L. The powerful drawing action which results isadequate to draw the wool from between the teeth of the large circle,and is, we have found, even superior to that produced by fluted rollsand leathers. In the case of the small circle, which holds its wool lesstenaciously, three dra.ving-1olls are sufficient, though we have foundthat this is the least number which can be depended upon to dosatisfactory work under all conditions.

(Z3 designates a supporting-frame intermediate of the drawing-heads, thesaid frame resting O11 extended portions (Z1 (Z5 of the said heads andbeing movably secured thereto by shouldered bolts passing through slotsThis arrangement allows the drawing-heads to be moved independently ofthe frame (Z3. Standards il di on the frame support a pair of horizontalrolls cl3 cl", the upper roll (ZS being yieldingly arranged upon thelower one d and pressed downwardly thereon by means of springs Zw in thetops of IOO IIO

' thestandards.' (See 3.) yOn the shafts of the two rolls areintermeshing gears e3 e4, and on the shaft of the lower one is abevelgear e5, which meshes with a bevel-gear e6, secured to a verticalshaft e7. Said shaft is jour- Vna'led in a sleeve es, secured to thesupporting-frame d3, and is rotated by meansof a sprocketfchain f4,engaging sprocket-wheels f3 and f5 on the shafts e7 and f, respectively.The chain is normally Yheld taut by means of a spring j7, attached tothe heade and to a studm, projecting from the under side of the dertomaintain the chain f4at its proper de-l gree of tautness, and for thispurpose said plate 'is provided, Fig. 11, with-a pivot-pin n',

extend-ing up into the bed-plate of the head d, and with clamping-screwsn2 n3, extending through circular slots in the cam-plate. When thecamplate is to be adjusted, the screws n2 n3 are loosened, the plateturned on its pivot to the required adjustment, and the screws thentightened to clamp the plate in place.

Guiding' troughs or conduits g4 g4 for the support of the sliver as itapproaches and leaves the rolls d8 C19 are adj ustably mounted betweenears g3 g3, formed on the frame d3. The trunnions of-said conduits areclosely-fit.- ted vin their bearings, so that when tilted to a certainposition the conduits will remain in that position. The trunnions areprovided outside the ears g3 with handles g5 g5, whereby the conduitsmay be tilted.- These guiding troughs or conduits are supplemented bypivoted funnels or bell-shaped conductors '122 i3, whose shanks 4/5 areloosely held in sleeves '116 i7, formed upon the heels of theguidingconduits.

The operation of the machine as applied to a Noble comb is bestillustrated in Fig. 10. The long wool from the teeth of the large circleor comb Z5 is drawn off between the rolls 7c3 7a4 765 k6, passingthrough the bell-guide adjacent thereto and along the guiding-troughthrough the horizontal rolls d8 Z9 and through the other trough andbell-guide to the dra-W- ing-rolls r s t. Here it meets the short woolfrom the smaller comb Z4, and the two are blended into one sliver inpassing between the latter rolls. This sliver is passed forward lintoacan for future operations.
